The work of preparing International Standards is normally carried out through ISO technical

12、 committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with

13、 the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed fo

14、r the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights

15、. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this d

17、ade (TBT), see the following URL: Foreword Supplementary information .The committee responsible for this document is ISO/TC 114, Horology, Subcommittee SC 1, Shock resistant watches.This third edition cancels and replaces the second edition (ISO 1413:1984), which has been technically revised with th

18、e following changes:a) added a third shock on the watch head (on the crown);b) added two free-fall shocks, including the bracelet.iv ISO 2016 All rights reservedBS ISO 1413:2016ISO 1413:2016(E)IntroductionThis International Standard is intended to allow the homologation test of watches rather than t

19、he individual control of all watches of a production batch. Indeed, assuming that each watch could comply with the minimum requirements without apparent damage, readjustment could still be made necessary because the test can lead to an alteration of the initial functions and rate of a complete watch

20、. ISO 2016 All rights reserved vBS ISO 1413:2016BS ISO 1413:2016Horology Shock-resistant wrist watches1 ScopeThis International Standard specifies the minimum requirements for shock-resistant wrist watches and describes the corresponding test method.It is based on the simulation of the shock receive

21、d by a wrist watch while falling from a height of 1 m onto a horizontal wooden floor (an equivalent surface is described in B.1.1).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated refe

22、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 3158, Timekeeping instruments Symbolization of control positionsISO 22810, Horology Water-resistant watches3 Terms and definitionsFor the purpose of th

23、is document, the following definitions apply.3.1shock-resistanceability to sustain impacts without damage3.2shock-resistant watchwatch that resists mechanical shocks according to this International Standards requirements3.3display componentselements of the watch which determine and display a physica

24、l value to the consumerEXAMPLE Hands, calendar disks, rotating cylinders, pointers or any other mechanical devices.Note 1 to entry: This includes any electro-optical display elements of the watch which determine or display, through their position, contrast, polarity, colour, sound or other propertie

25、s, a physical value to the consumer.3.4residual effectoccurrence of failures or changes in the watch functions as a result of exposure to shocksNote 1 to entry: Any kind of failures are considered as residual effects. In order to determine the degree of shock resistance, residual effects are divided

26、 into permanent residual effect (3.5) and reversible residual effects (3.6).3.5permanent residual effectchanges in the display information and in the watch functions which remain present after the testNote 1 to entry: The consumer does not have the ability to remedy said failures or reset the functi

27、ons without the intervention of a professional watch service. These failures may include the following: disconnected or repressed gear train of the hour and/or minute mechanism;INTERNATIONAL STANDARD ISO 1413:2016(E) ISO 2016 All rights reserved 1BS ISO 1413:2016ISO 1413:2016(E) sliding of the hour

29、unctions which are temporarily present after the testNote 1 to entry: The consumer has the ability, without professional assistance, to reset or readjust the changes onto initial values or conditions. Displacements can be reset manually to the initial position or initial value by the consumer using

30、the time or calendar setting mechanism.Note 2 to entry: Although adjustable failures are classified as less critical, certain limits of adjustable failures of the display or of the watch function shall be considered.EXAMPLE Displaced minute hand due to a sliding cannon pinion and displaced calendar

31、disk due to a sliding jumper spring.4 Test conditions4.1 Test temperatureThroughout the test period, the ambient temperature shall be between 18 C and 25 C.4.2 Water resistanceWatches labelled water-resistant shall comply with ISO 22810.For watches being tested and labelled in compliance with ISO 22

32、810, the water resistance must remain intact after the shock exposures on watch heads. See 5.2.4.3 Shock characteristicsThe test apparatus for the three first shocks (shock test apparatus) and the test apparatus for the free-fall shocks shall comply with shock characteristics described in Annex A.If

33、 the test apparatus for the free-fall shock cannot be checked according to Annex A, its impact surface shall be identical to the impact surface of the sabot.4.4 Test apparatus4.4.1 MaterialSabot (shock test apparatus) and impact plate (free-fall test apparatus) shall be made with the same material (

34、see B.1.1).4.4.2 Shock test apparatusAn example of test apparatus for the shocks is described in Annex B and shall comply with its specifications.4.4.3 Free-fall test apparatusThe free fall shall be from a height of 1 m.2 ISO 2016 All rights reservedBS ISO 1413:2016ISO 1413:2016(E)An example of test

All functions of push buttons or sliding switches, e.g. Start Stop Reset of chronographs; On Off function for buzzer, lighting or any other function present, shall work correctly. Functional elements providing

40、 any mechanical, vibrating, acoustic, or any other signals shall be functional. Screw-down crowns or push buttons (if applicable) shall be set to the screwed-down position, as in normal use. Other crowns shall be set in the normal use position.5 Test method5.1 GeneralWatches to be tested shall be se

41、parated for two different procedures. Shock test procedure applies to functional watch heads only and shall be used for shocks 1, 2 and 3.NOTE Shock 3 can be applied on a different watch head than that used for shock 1 and 2. Free-fall test procedure applies to complete watches with bracelets (inclu

42、ding movement or equivalent dummy) and shall be used for free-fall shocks 1 and 2.Flowcharts summarizing the following procedures (5.2 and 5.3) are described in Annex D.5.2 Procedure for shocks on watch heads5.2.1 GeneralThe watch heads shall be tested without having a bracelet or a strap attached.
